Fox had cast Lawrence in the supporting role of Mystique months before Lionsgate cast her in the leading role of Katniss Everdeen. Fox had the right to exercise their sequel option on Lawrence and start filming the X-Men sequel this fall, thus screwing up Lionsgate's plan to get Catching Fire started in time to make its already announced 2013 release date.

Matthew Vaughn will direct the next X-Men film, while Lionsgate is still trying to work out a deal with Gary Ross to reprise directing duties for the Hunger Games sequel.
